[PATCH 0/5] reset rework, 2nd try

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I took me a while to see the real issues Chris has been complaining about, but I
think the reworked patches take them all into account now. The big change is
that the wedged check at the beginning of intel_ring_begin stays, but gets
improved by properly deciding betweein -EIO and -EAGAIN. I've checked all the
callsites and couldn't find any issues.

Comments, flames, reviews and testing reports highly welcome.

I've also pushed the latest version of this to the reset-rework branch of my
personal git repo.

Cheers, Daniel

  drm/i915: don't trylock in the gpu reset code
  drm/i915: non-interruptible sleeps can't handle -EGAIN
  drm/i915: don't hang userspace when the gpu reset is stuck
  drm/i915: properly SIGBUS on I/O errors
  drm/i915: don't return a spurious -EIO from intel_ring_begin
